Mapping attributes from one entity to another?

I want to be able to collect user-input data in one master entity, and then split up the elements that have been captured into other entities. Is this possible?

For example: Entity 1 has attributes of Name, Address, State, City, Zipcode Can I map just Name and Address to Entity 2 after entity 1 has been committed?

If possible, how would I do so?

Thanks!
